From the San Francisco Chronicle:
I'm not sure whether the Pirates are actually willing to move Gonzalez (the Post Gazette reports that they're not discussing a Gonzalez trade with anyone), but they should be. He's not horribly young and would have more value to a contending team than he'd have to the Pirates. If the Pirates are on the verge of contending in a couple years, they can worry about developing or acquiring a closer then. Now, they need a better core of starting pitchers and offensive players. The Giants probably can't help much with that, but the Dodgers certainly can.
